<P>PROBLEM TO BE SOLVED: To provide a titanium alloy which has good workability and corrosion resistance that is the same as or better than before and has a rate of content of a platinum group element lower than before to be economical, and in which erosion hardly progresses, when damage in the surface defect or the like thereof occurs, with the damage as a starting point. <P>SOLUTION: The titanium alloy comprises, by mass: 0.01 to 0.15% of a platinum group element; 0.001 to 0.10% of a rare earth element; and Ti and impurities as the balance. Preferably, the titanium alloy comprises, by mass, 0.05 to 1.00% of Co in place of a portion of the Ti, and preferably comprises, by mass, the platinum group element of 0.01 to 0.05%. Moreover, preferably, the platinum group element is Pd and the rare earth element is Y. <P>COPYRIGHT: (C)2013,JPO&INPIT |
